Written by

Elliot Stent

Free The Tone make some stunning pedals and this Ambi Space is their first forey into Digital Reverb. You can dial in anything from light spring reverb to FTT's custom Cave tone.

You can store up to 4 of your favourite settings and call them back using MIDI programming or by using the right hand switch. The sound can be controlled by using the 4 dials: Pre Delay, Decay, Tone and Mix.

6 types of tone

This pedal coems pre set with 6 dfiferent sounds. Spring, Plate, Room, Hall, Cave and Serene. Each of these has a diferent character to it and adds a new sound to your gigging repertoire. This could very well be the only reverb you need... no more relying on the reverb built into your amp or the deck.  

Chappers & The Captain "Free The Tone"...

Here's what Free The Tone have to say about this pedal

By using FTT’s original algorithm, the AMBI SPACE combines various elements to achieve a mechanism for producing complex reverberation, through the use of a 32-bit dual core chip and a 32-bit high precision DSP. While the high quality, natural and musical sounding reverberation realized in this compact device can of course be used for electric guitars and basses, as well as for acoustic guitars and vocals, it is equally at home in other situations, such as recording and mixing. In FTT’s newly developed and original reverb sounds “CAVE” and “SERENE”, the early reflections and late reverberation are added in multiple steps to realize a complex harmonic structure comprising enhanced frequency components, all of which creates an almost magical, transparent and spatial sounding reverb like you’ve never heard before. These new reverb sounds will stimulate your imagination.

By combining all of the analog and digital know-how accumulated so far by Free The Tone, the reverb effects unit AMBI SPACE was finally born after a long development period. Try it out and feel its sound.
